Description AKRAPOVIC MTP-BM/SS/2H Exhaust System Evolution Line (Stainless Steel) BMW 340i (F30 / F31) / 440i (F32 / F33) EC Approval The Akrapovic Evolution exhaust system for the BMW 340i represents a precise integration of advanced engineering, premium materials, and proven exhaust technology. Manufactured from high-quality austenitic stainless steel, the system features a dual central link pipe configuration, replacing the factory single-pipe layout to optimize exhaust gas flow. The system is completed with carbon fibre tailpipes, enhancing the vehicle’s rear aesthetics with a refined and performance-oriented appearance. The dual-mode, ECU-controlled valve system delivers a stock-level sound during normal cruising and transitions to a deeper, sportier tone under dynamic driving conditions. The Evolution system replaces the factory exhaust from the catalytic converters rearwards, providing measurable gains in power and torque along with weight reduction. Please be aware that both part numbers (MTP-BM/SS/2H and E-BM/SS/2) must be ordered. The system is split into two codes solely due to packaging requirements.
